Study On Insect Diversity And Its Influencing Factors In Jiamusi Airport And Surrounding Areas

Jiamusi Airport located in the east of Jiamusi City,Heilongjiang Province,which is known as ?the best ecological charm city in China?.Its latitude is N46°50'24 " and the longitude is E130°27'42".This paper studies the insect diversity and influencing factors of Jiamusi Airport.The details are as follows:Objective: To investigate the distribution and occurrence characteristics of different insects by analyzing the resources and diversity of different habitat insects in Jiamusi Airport,determine the distribution range of different insect species,and clarify the occurrence rules of insect populations in different habitats of Jiamusi Airport,and determine the advantages of Jiamusi Airport lawn area.Insect populations can provide a basis for the number of insects at Jiamusi Airport.By studying the relationship between airport insects and birds and their habitats,we propose pest control recommendations to minimize the activity of insectivorous birds in the airport,thus improving the level of bird strike prevention and control at the airport.Methods: Investigation of insect diversity and investigation of plant influencing factors in Jiamusi Airport,using a sweeping net method,net catching method and observation method as the main investigation methods,combined with yellow disk method and collecting method for auxiliary investigation.At night,black light traps were used for moth collection;the survey of bird influence factors mainly used the sample line method.The collected data was collated and quantitative statistics and analysis were performed using DPS 7.0 software.Results: 4779 species were collected from the four habitats in Jiamusi Airport and surrounding areas,belonging to 146 species of 133 genera,16 families,71 families.Shannon-Wiener diversity index(H)of four habitat insects ranked from high to low: shrub area>forest area>landland area>turf area;Pielou evenness index(J)is arranged from high to bottom: farmland area> Shrub area > forest area > turf area;dominance index(D)is arranged from high to bottom: shrub area > farmland area > forest area > lawn area.The similarity(S)between the airport grassland and the shrub is 0.663,and the similarity(S)between the airport lawn area and the farmland area is 0.229.In the relationship between airport insects and airport plants,the order of the number of the four species in the four communities is: Elymus sibiricus community> Rumex patientia community>Sonchus arvensis community> Taraxacum mongolicum community;the number of cabbage butterflies.The order from high to low is: Elymus sibiricus community> Taraxacum mongolicum community> Rumex patientia community> Sonchus arvensis community;the order of the number of Spodoptera moths from high to low is: Rumex patientia community>Elymus sibiricus community> Sonchus arvensi community > Taraxacum mongolicum community;the order of the number of the family carp from high to low is: Elymus sibiricus community> Rumex patientia community> Sonchus arvensis community>Taraxacum mongolicum community;the order of the number of the red-brown leg-legged from high to low is: Elymus sibiricus community > Rumex patientia community > Taraxacum mongolicum community> Sonchus arvensis community.In the relationship between airport insects and airport birds: the order of the number of the Hirundo rustica in the five dominant insects from high to low is: the occurrence of the Catantops pinguis > the occurrence of Acheta domesticus > the occurrence of the Pieris rapae >the occurrence of Heliothis dipsacea> the occurrence of the Harmonia axyridis;the order of the number of Motacilla alba from high to low is: the occurrence of the Catantops pinguis> the occurrence of Acheta domesticus >the occurrence of Heliothis dipsacea> the occurrence of the Pieris rapae> the occurrence of the Harmonia axyridis;the order of the number of Lanius cristatus from high to low is: the occurrence of Acheta domesticus > the occurrence of the Catantops pinguis>the occurrence of the Pieris rapae > the occurrence of the Harmonia axyridis> the occurrence of Heliothis dipsacea;The order of quantity from Upupa epops is: the occurrence of the Pieris rapae> the occurrence of Acheta domesticus > the occurrence of Heliothis dipsacea>the occurrence of Catantops pinguis> the occurrence of the Harmonia axyridis;the order of the number of Alauda arvensis from high to low is: the occurrence of Catantops pinguis> the occurrence of Acheta domesticus > the the occurrence of the Pieris rapae> the occurrence of Heliothis dipsacea > the occurrence of the Harmonia axyridis.Conclusion:Among the four species of habitat insect communities in Jiamusi Airport and surrounding areas,Lepidoptera,Coleoptera,Homoptera,Orthoptera,and Hymenoptera are the main groups.The diversity index(H)of the four habitats was the highest in the shrub area and the lowest in the turf area.The Pielou evenness index(J)was the highest in the farmland area and the lowest in the turf area.The dominance index(D)was the highest in the shrub area and the lowest in the turf area.In the similarity index(S),the similarity index between the lawn area and the shrub area was the highest,and the similarity index between the lawn area and the farm area was the lowest.In the study of the relationship between dominant insects and airport plant communities in Jiamusi Airport,the number and species of dominant species were the highest in the Elymus sibiricus community,and the number and species of dominant species in the Taraxacum mongolicum community were the least.In the study of the relationship between airport insects and airport birds,the number of birds was the highest in the occurrence period of the Catantops pinguis.Through the research of this project,it can provide a reference for the prevention and control of insects in bird defense of Jiamusi Airport.
